Towards better integration of wood protection in the forestry wood industry chain - a case study on hybrid poplar
2019 - IRG/WP 19-50359
Wood and wood products are limited in service life as in the forest ecosystem trees at end of their life are degraded to re-enter the bio-geochemical cycle. Humans can select wood species with a level of natural durability fit for an envisaged end use. Mainly those applications that require a long service life under conditions that are similar to those at soil level in a forest ecosystem have been...

Chemical composition and performances of slow pyrolysis by-product from sugarcane bagasse for wood protection
2020 - IRG/WP 20-30752
Pyrolysis distillate or bio-oil, a by-product of biomasses’ slow pyrolysis in the char-making process, has been traditionally used as bio-pesticides by Asian farmers. Due to its large composition of bio-active chemicals, bio-oil obtained from various biomass has become of interest in many applications, including wood protectants. This study aims to characterize the chemical composition of bio-oi...

Comprehensive protection of timber in seawater
2020 - IRG/WP 20-10970
The hazard of wood in seawater can be divided into two areas: Below the water level, shipworm (Teredo navalis) and gribble (Limnoria lignorum) can attack non-resistant or insufficiently protected wood; above the water level, there is a risk by wood-destroying fungi and, to a lesser extent, insects. In a national project funded by the Deutsche Bundesstiftung Umwelt (DBU, German Federal Environmenta...

Extraction, identification and antifungal activity of polar extractives originated from various wood species
2020 - IRG/WP 20-20673
Extractives are non-cell wall small molecules present in wood and other lignocellulosic materials that can be removed by solvents. Although they represent a minor fraction in comparison with the structural cell wall components, they are an important source of functional groups or molecules with bioactivity or antioxidant properties, that could be used in medicine, cosmetic or wood preservation. T...

DuraSoft Project: a multidisciplinary approach for softwood protection
2021 - IRG/WP 21-50367
Over the course of millennia, fishing and agro-pastoral activities have produced unique housing types in the Italian lagoons and in the Slovenian highlands where the use of wood is predominant. They are associated with wooden service infrastructures such as piers, moorings, piling and fences. However, the existence of these structures and the associated cultural heritage are subject to constant ...

A new approach to wood protection: Potential of biologically synthesised CuO and ZnO nanoparticle formulation as a wood preservative
2022 - IRG/WP 22-30758
Even though metal nanoparticles are effective in protecting wood, they are less preferred, as they are synthesised using methods which are expensive and are not environmentally friendly. Biological synthesis of nanoparticles using plants, fungi, yeast, bacteria and viruses, has been accepted as an alternative approach and is referred to as green synthesis. Utilization of biologically synthesised n...

CIOL®-protection of wood – an update
2022 - IRG/WP 22-40932
Most commercial wood species from the northern European region are of low natural durability. Products from these wood species for outside applications need therefore protection to increase their service life. This protection should be free of biocides, come from renewable resource, have great performance and hold a low consumer price. A mixture of water, sorbitol and citric acid has the potential...

Extraction of fungal colorants for their use in coloured coatings for wood
2022 - IRG/WP 22-40938
Microorganisms are highly interesting for the production of useful metabolites. Such metabolites are e.g. colorants, that can easily be produced on industrial scale and low material costs. To date some microbial produced colorants are used in textile- and food industry because of their low toxicity and sustainability compared to synthetically produced colorants. However, little is known about the ...

Effect of nano-particle characteristics and concentration on UV protection of timber: A field exposure test
2022 - IRG/WP 22-40941
Wood has a well-known susceptibility to ultra-violet light degradation, leading to premature replacement. A variety of products have been developed to protect against this damage, but most provide less than 12 months of protection and must be regularly reapplied. Developing improved coatings would help reduce wood losses and reduce maintenance costs. Nano-particles have a variety of attractive pro...

Efficacy of a wide-spectrum plant bio-based anti-termite product - Laboratory trials
2023 - IRG/WP 23-11024
Compared to the number of timbers available, the list of wood species resistant to termites is rather limited and largely composed of tropical timbers. In addition, due to climate change and environmental degradation, together with global trade, a significant global expansion of termites is predicted along with the economic losses due to their activities. Therefore, there is a demand to find produ...

Moisture performance of wooden shingles tested on the Golobar cable yarding
2023 - IRG/WP 23-20704
Wood is a traditional roofing material in Europe and other parts of the world. In the 17th century, wooden roofing was generally used on more important buildings, but today it is mainly used on huts and houses in the Alpine regions. As wooden roofing is expensive, we investigated the possibility of extending the service life of the roofing through material selection and details. The roof of the Go...
